Well I'm at 99,000 miles now and going back to school in a week without the car so it will be sitting for a little while but I'll have the parents drive or at least start it weekly. I've done the normal stuff like fuel filter, new plugs, wires, seafoam, regular 3,000 mile oil changes but is there any other stuff I should do as far as a kind-of 100k tuneup? I was thinking I should get my trans flushed since its recommended like every 30,000 miles and I don't know the last time it was done. Should I go to ford or the Valvoline place I usually go to who's running a special? I was also thinking of doing the 02 sensors. There are 4 correct? Would either two be better to replace or should I just do all 4 and any brand recommendations? Any other ideas just as regular maintenance and good tune up stuff? Thanks guys.

One thing we would do on a dodge trans is that you drain the fluid out, BUT you put in a 50/50 mix of new and old fluid, puting in all new fluid messes it up. This was actually the recommended procedure from Chrysler.
